Code U1141 RAM Description

The U1141 RAM code indicates that the Electronic Stability Program (ESP) system in the vehicle has lost communication with the Engine Control Module (ECM) regarding torque requests. The ESP system is responsible for enhancing vehicle stability by detecting and reducing skidding, and it relies on information from the ECM to adjust torque as needed. When the ESP system cannot communicate with the ECM, it may not be able to respond effectively to changes in driving conditions, potentially compromising the vehicle's stability and safety.
